If the administrator wants to allow users to edit the description metadata for the file foo, the administrator can set the appropriate permissions for foo/.../description, and keep foo read-only. >>Kevin Bowen wrote: >>> If you're sysadmining a multiuser reiser4 box, and your users are >>> able to modify the metadata of files they don't own, then you go to >>> sysadmin purgatory. Actually, you could use something like unionfs to allow users to keep their own annotations without affecting everyone else's. -- Hubert Chan - http://www.uhoreg.ca/ PGP/GnuPG key: 1024D/124B61FA Fingerprint: 96C5 012F 5F74 A5F7 1FF7 5291 AF29 C719 124B 61FA Key available at wwwkeys.pgp.net.
